Multifuel motor mounts (isolation mounts, rubber mounts, engine mounts)

[cattlerepairman]

Ready to start engine removal. What to do about the old-age senile isolation mounts? I see left ones on an auction site (right and left are different sizes...) and they do not feature prominently on any vendor's list. Are there generic replacements that will work as well?

 

[Jeepsinker]

Right and left should be the same. It's the top and bottom that are different sizes.

Don't mean to hijack the thread, but I'm having the same problem on the under the radiator mounts on my M54.

They are different for the M44A1 and M44A2 crossmembers in the front. Rears are the same for A1 and A2.

Go into the TM and find the NSN's for what you have and do an internet search. They are available pretty inexpensively. I would never reuse them if they show any cracking or dry rot.

A2:


EDIT:

Found some better pictures where we had previously discussed the A1 / A2 crossmembers: http://www.steelsoldiers.com/showth...tween-M35A2s&p=1589557&viewfull=1#post1589557

I admit, I never used the -P manuals, but they are indeed helpful. Thanks for that reminder.

The M35A2 has 8 engine mounts (isolators):
4x NSN 19207 7538641 (upper mount)
4x NSN 19207 7538640 (lower mount)

The info is in TM9-2320-361-34P and can, for example, be found at http://www.tnjmurray.com/militaryvehicles/manuals/TM9-2320-361-34P-MF.pdf

Happened to be looking into this today and came across this thread.

TM 9-2320-209-34P Lists the following

In Figure #2 Page 6 Engine Mounts - Multifuel (This is for LDS427-2 Only)

4 pcs 7538640 Mount, Resilient, Front & Rear For LDS & LDT Engines
2 pcs 7538641 Mount, Resilient, Upper Rear 4 pcs needed for LDT Engines
2 pcs 10872097 Mount, Resilient, Used on LDS427-2 Only

Figure #5 shows the requirements for LDT465 engines.

Hope this might clarify the use or need for P/N 10872097

Has anyone found "polyurethane" motor mounts for the Deuce ? Or transfer-case mounts ?

 

[MuleMac01]

Think thes are hard to find try finding some for the OA-331 engine lol motor mounts, and radiator mounts took me a month to find them across 6 different parts houses.

I thought the OA-331 engine used standard motor mounts ? At least mine sure looked like they where standard type mounts.
I still have one of my M34 1954 REO's left. I'll try and remember to check them tomorrow.

I already bought a set of motor mounts for my M35A2, so I won't be trying this myself. But the mounts look like standard Semi-truck mounts. I should measure them and see if there are regular "civilian" mounts available. Our buses used this type too. All you would need is the proper size bolt hole and the correct height.

I was researching isolation mounts for my cab mounted computer and came across a manufacturer that may be worth looking at. I would think for the deuce application, as long as it meets the specs it doesn't have to be a military part (unless you need that for your restoration). Anyways, maybe worth a look: https://www.novibes.com/Products

OA-331 engine uses the following:

TM 9-2320-209-34P

Figure #3 Page #7

7538640 2 pcs (Same P/N as for multifuel)
7538641 2 pcs ""
7538639 2 pcs Insulator, Mounting (Does not look to be available anywhere - but may be the same as the square radiator insulators used under the radiator on Deuces)
